September 9, 2020 -  Just now finished wiring up and testing a basic instruction decoder. I am using 4 switches to simulate the instruction register at the moment but will swap those out for the real register soon. The picture shows a 0110 as the simulated instruction and with this 4 bit number fed to the hard wired decoder it will pass the signal from the selected State Machine output and proceed with the instruction logic.
